[0054] Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings, which show representative embodiments of the present invention and do not limit the present invention.

[0055] As Figure 1 shown, the present invention provides a refrigerated container 100, which can be used in the cold chain transportation industry, especially for transporting fresh goods such as fruits and vegetables. The refrigerated container 100 can be a 45'-long container to accommodate more goods. The refrigerated container 100 includes a box body 110, and the box body 110 is used for storing goods. Combining Figure 2 and Figure 3 shown, the box body 110 includes an inner wall plate 111, an outer wall plate 112, and a heat insulation layer 101. The heat insulation layer 101 is located between the inner wall plate 111 and the outer wall plate 112 to enhance the freshness preservation performance of the box body 110.

[0056] An air conditioning device 102, a refrigeration device 103, and a storage device 130 are also provided in the box body 110. The storage device 130 is used for storing goods. The refrigeration device 103 is located between the storage device 130 and the inner wall plate 111. For example, the inner wall plate 111 includes an openable inner end wall 115, and the refrigeration device 103 is located between the inner end wall 115 and the storage device 130. The refrigeration device 103 is used to adjust the temperature inside the box body 110. For example, the refrigeration device 103 can deliver cold air to lower the temperature inside the box body 110.

[0057] As Figure 6As shown, the controlled atmosphere device 102 is located between the storage device 130 and the inner wall panel 111. The controlled atmosphere device 102 and the refrigeration device 103 can be located on the same side of the box body 110. The controlled atmosphere device 102 can also be located between the inner end wall 115 and the storage device 130. The controlled atmosphere device 102 can be communicated with the storage device 130 through a pipeline 108. The controlled atmosphere device 102 can adjust the composition and content of the gas in the storage device 130 to effectively inhibit the respiration of fruits and vegetables, so that the fruits and vegetables are in a hibernation state, thereby extending the fresh-keeping time.

[0058] Further, the storage device 130 includes an inner plate and an outer plate, and the inner plate and the outer plate are spaced apart. Both the inner plate and the outer plate can be made of a food-grade material with rapid temperature conduction. The outer plate can include an outer end plate, and the outer end plate and the inner end wall 115 can be substantially parallel. The outer end plate can be spaced from the inner end wall 115. A refrigeration device 103 and a controlled atmosphere device 102 can be provided between the outer end plate and the inner end wall 115. Further, the refrigerated container 100 further includes a reinforcing rib, and the reinforcing rib is located between the outer plate and the inner wall and connects the outer plate and the inner wall panel 111. Thus, the connection strength between the outer plate and the inner wall panel 111 can be improved.

[0059] The outer plate and the inner wall panel are spaced apart. The reinforcing rib can include a plurality of end reinforcing ribs 184, and the outer end plate and the inner end wall 115 are spaced apart in the height direction of the refrigerated container 100. The plurality of end reinforcing ribs 184 are located between the outer end plate and the inner end wall 115 and connect the outer end plate and the inner end wall 115. Thus, the connection strength of the end of the storage device 130 can be improved.

[0060] As Figure 4 shown, the outer plate can further include an outer side plate 153, and the inner wall panel 111 can further include an inner side wall 114. The outer side plate 153 and the inner side wall 114 can be substantially parallel. The outer side plate 153 can be spaced from the inner side wall 114. Combining Figure 2 shown, the reinforcing rib includes a plurality of side reinforcing ribs 183, and the outer side plate 153 and the inner side wall 114 are spaced apart in the height direction of the refrigerated container 100. The plurality of side reinforcing ribs 183 are located between the outer side plate 153 and the inner side wall 114 and connect the outer side plate 153 and the inner side wall 114. Thus, the connection strength of the side of the storage device 130 can be improved.

[0061] The outer plate can further include an outer top plate 152, and the inner wall panel 111 can further include an inner top wall 113. The outer top plate 152 and the inner top wall 113 can be substantially parallel. The outer top plate 152 can be spaced from the inner top wall 113. The reinforcing rib includes a plurality of top reinforcing ribs 182, and the outer top plate 152 and the inner top wall 113 are spaced apart in the height direction of the refrigerated container 100. The plurality of top reinforcing ribs 182 are located between the outer top plate 152 and the inner top wall 113 and connect the outer top plate 152 and the inner top wall 113. Thus, the connection strength of the top of the storage device 130 can be improved.

[0062] The inner plate and the outer plate are spaced apart to form an interlayer 131. Preferably, internal reinforcing ribs 185 are further provided between the inner plate and the outer plate to improve the structural strength of the storage device 130 itself. The inner plate may further include an inner end plate, an inner side plate 143, and an inner top plate 142. The inner end plate and the outer end plate may be substantially parallel, and the inner end plate and the outer end plate are spaced apart to form an end interlayer. Combining Figure 5 As shown, the inner side plate 143 and the outer side plate 153 may be substantially parallel, and the inner side plate 143 and the outer side plate 153 are spaced apart to form a side interlayer. The inner top plate 142 and the outer top plate 152 may be substantially parallel, and the inner top plate 142 and the outer top plate 152 are spaced apart to form a top interlayer. The end interlayer, the side interlayer, and the top interlayer may communicate with each other.

[0063] The inner plate further has a plurality of first through holes 132, and the first through holes 132 communicate with the interlayer 131. The storage device 130 may include a storage space surrounded by the inner plate for storing goods. Preferably, the inner end plate may have a plurality of first through holes 132, and the plurality of first through holes 132 may communicate the end interlayer and the storage space. The inner side plate 143 may have a plurality of first through holes 132, and the plurality of first through holes 132 may communicate the side interlayer and the storage space.

[0064] The outer plate has an inner surface and an outer surface. The inner surface is located in the interlayer 131, and the outer surface faces the inner wall plate 111. The refrigeration device 103 may cool the interior of the box body 110, and the temperature inside the storage device 130 may be higher than the temperature outside the storage device 130. Thus, the water in the warmer air in the interlayer 131 will condense into water droplets on the inner surface of the outer plate when it meets the cold, and the water droplets exist in the interlayer 131 without dripping onto the surface of the fruits and vegetables. The air contains water vapor, such as the water vapor generated by the respiration of fruits and vegetables. The water vapor can enter the interlayer 131 through the plurality of first through holes 132. The water vapor can enter the interlayer 131 through the plurality of first through holes 132 of the inner plate, and the water vapor can condense on the inner surface of the outer plate to form water droplets. In this way, the water droplets are located in the interlayer 131 and do not drip onto the fruits and vegetables, preventing the fruits and vegetables from rotting and deteriorating.

[0065] Specifically, the outer end plate has an inner surface. Water vapor can enter the end interlayer through a plurality of first through holes 132 in the outer end plate, and the water vapor can condense on the inner surface of the outer end plate to form water droplets. In this way, the water droplets are located in the end interlayer without dripping onto the fruits and vegetables, preventing the fruits and vegetables from rotting and deteriorating. The outer side plate 153 has an inner surface. Water vapor can enter the side interlayer through a plurality of first through holes 132 in the inner side plate 143, and the water vapor can condense on the inner surface of the outer side plate 153 to form water droplets. In this way, the water droplets are located in the side interlayer without dripping onto the fruits and vegetables, preventing the fruits and vegetables from rotting and deteriorating. The outer top plate 152 has an inner surface. Water vapor can condense on the inner surface of the outer top plate 152 to form water droplets. In this way, the water droplets are located in the top interlayer without dripping onto the fruits and vegetables, preventing the fruits and vegetables from rotting and deteriorating.

[0066] According to the refrigerated container of the present invention, the refrigerated container includes a box body. The box body includes an inner wall plate, an outer wall plate, and a heat insulation layer. An air conditioning device, a refrigeration device, and a storage device are further provided in the box body. The refrigeration device and the air conditioning device are both located between the storage device and the inner wall plate. The storage device is communicated with the air conditioning device. The storage device includes an inner plate and an outer plate. The inner plate and the outer plate are spaced apart to form an interlayer. The inner plate has a plurality of first through holes, and the first through holes are communicated with the interlayer. In this way, water vapor in the air can enter the interlayer through the first through holes. The water vapor forms water droplets in the interlayer, and the water droplets will not form and drip in the storage space inside the storage device, preventing the goods in the storage space from rotting and deteriorating, and improving the freshness preservation performance of the refrigerated container.

[0067] Furthermore, the respiration of fruits and vegetables will also generate gases such as carbon dioxide. Therefore, the storage device 130 further includes a sealing plate. The sealing plate can separate the storage space of the storage device 130 from the refrigeration device 103. During transportation, the cold air generated by the refrigeration device 103 will not enter the storage device 130. The fruits and vegetables in the storage device 130 generate gases due to respiration, resulting in a change in the gas composition inside the storage device 130. The air conditioning device 102 is activated to adjust the gas composition in the storage device 130 to maintain a good storage environment for the fruits and vegetables, and the air conditioning device 102 is used to adjust the storage device 130 and will not be pumped out to participate in the cold air circulation process of the refrigeration device 130.

[0068] As Figure 2 and Figure 3 shown, the refrigerated container 100 further includes a box door 105. The box door 105 and the refrigeration device 103 are respectively located at both ends of the box body 110 along the length direction of the box body 110. The storage device 130 further includes an open opening 133, and the opening 133 faces the box door 105. Goods can enter the storage space of the storage device 130 through the box door 105 and the opening 133.

[0069] The sealing plate can connect the outer plate and the inner wall plate 111, and the sealing plate, the outer plate and the inner wall plate 111 together form a gas passage 171. Preferably, the sealing plate can be perpendicular to the length direction of the refrigerated container 100. The sealing plate includes a top sealing plate 162 (the top sealing plate 162 is shown in Figure 6 ), and a side sealing plate 163. The side sealing plate 163 is connected to the outer side plate 153 and the side sealing plate 163 is perpendicular to the outer side plate 153.

[0070] The length direction of the side sealing plate 163 is substantially parallel to the height direction of the refrigerated container 100, and the width direction of the side sealing plate 163 is substantially parallel to the width direction of the refrigerated container 100. One side of the side sealing plate 163 along the width direction of the refrigerated container 100 is connected to the outer side plate 153, and the other side of the side sealing plate 163 along the width direction of the refrigerated container 100 is connected to the inner wall 114. As Figure 4 and Figure 5 shown, the storage device 130 includes two outer side plates 153 and two side sealing plates 163. The two outer side plates 153 are arranged opposite to each other along the width direction of the refrigerated container 100. The two side sealing plates 163 and the two outer side plates 153 are respectively connected. Further, the storage device 130 includes side bending plates, and the inner side plate 143 is integrally formed with the side bending plates. The side bending plates and the side sealing plates 163 can be connected together by welding.

[0071] As Figure 6 and Figure 7 shown, the top sealing plate 162 is connected to the outer top plate 152 and the top sealing plate 162 is perpendicular to the outer top plate 152. The length direction of the top sealing plate 162 is substantially parallel to the width direction of the refrigerated container 100, and the width direction of the top sealing plate 162 is substantially parallel to the height direction of the refrigerated container 100. The bottom of the top sealing plate 162 is connected to the outer top plate 152, and the top of the top sealing plate 162 is connected to the inner top wall 113. The storage device 130 further includes top bending plates, and the inner top plate 142 is integrally formed with the top bending plates. The top bending plates and the top sealing plate 162 can be connected together by welding.

[0072] The gas passage 171 includes a top gas passage 172. The inner top wall 113, the outer top plate 152 and the top sealing plate 162 together form the top gas passage 172. The length direction of the top gas passage 172 is substantially parallel to the length direction of the refrigerated container 100, and the width direction of the top gas passage 172 is substantially parallel to the width direction of the refrigerated container 100. The top gas passage 172 can be communicated with the air outlet of the refrigeration device 103. The cold air discharged by the refrigeration device 103 can enter the top gas passage 172.

[0073] As Figure 4As shown, the gas passage 171 includes a side gas passage 173, and the inner side wall 114, the outer side plate 153, and the side sealing plate 163 can jointly form the side gas passage 173. The length direction of the side gas passage 173 is substantially parallel to the height direction of the refrigerated container 100, and the width direction of the side gas passage 173 is substantially parallel to the width direction of the refrigerated container 100. The side gas passage 173 communicates with the top gas passage 172, and the cold air in the top gas passage 172 can enter the side gas passage 173.

[0074] As Figure 6 shown, a fuel tank 104 is further provided in the box body 110. The fuel tank 104 communicates with the refrigeration device 103 to provide energy for the refrigeration device 103, so as to be applied to land transportation. A partition is further provided inside the box body 110, and the partition can separate the fuel tank 104 and the storage device 130. The gas passage 171 further includes an end gas passage 174, and the end gas passage 174 is located between the outer end plate and the inner end wall 115. Of course, the refrigerated container 100 may not be provided with a fuel tank to be applied to sea transportation or combined sea and land transportation.

[0075] The outer end plate and the box door 105 are respectively located at both ends of the box body 110 along the length direction of the refrigerated container 100. The outer end plate is close to the front end of the refrigerated container 100. The outer end plate, the partition, and the two inner side walls 114 jointly form the end gas passage 174. The length direction of the end gas passage 174 is substantially parallel to the height direction of the refrigerated container 100, and the width direction of the end gas passage 174 is substantially parallel to the width direction of the refrigerated container 100. The end gas passage 174 communicates with the side gas passage 173, and the cold air in the side gas passage 173 can enter the end gas passage 174.

[0076] During the transportation of fruits and vegetables, the gas passage 171 is not connected to the inside of the storage device 130. The sealing plate separates the gas passage 171 and the opening 133 to prevent the gas in the gas passage 171 from entering the inside of the storage device 130 through the opening 133. In this way, the cold air in the gas passage 171 will not be confused with the gas in the storage device 130, avoiding the waste gas generated by the respiration of fruits and vegetables from circulating and affecting the refrigeration effect, and also avoiding the cold air generated by the refrigeration device 103 from interfering with the operation of the controlled atmosphere device 102.

[0077] Specifically, the top sealing plate 162 separates the top gas channel 172 and the opening 133, and the top sealing plate 162 can prevent the cold air in the top gas channel 172 from entering the opening 133. The side sealing plate 163 separates the side gas channel 173 and the opening 133, and the side sealing plate 163 can prevent the cold air in the side gas channel 173 from entering the opening 133. The gas channel 171 communicates with the air outlet of the refrigeration device 103. In this way, the cold air discharged from the refrigeration device 103 can smoothly enter the gas channel 171. The gas channel 171 can also flow back to the refrigeration device 103 to enable the refrigeration device 103 to refrigerate in a cycle. The gas channel 171 is located between the storage device 130 and the box body 110 to provide sufficient space for the flow of gas and can effectively exchange heat with the storage device 130.

[0078] Furthermore, the goods in the storage device 130 will not interfere with the flow of the cold air in the gas channel 171, ensuring the refrigeration effect, preventing temperature differences from occurring during the flow of the cold air, preventing the fruits and vegetables far from the refrigeration device 103 from rotting, and preventing the fruits and vegetables in the storage device 130 from maturing to different degrees due to the action of different temperatures, thus ensuring the economic value of the goods. In order to make the contact area between the gas and the storage device 130 larger, the gas channel 171 is arranged around the storage device 130. Thereby, the occurrence of different degrees of maturation of the fruits and vegetables due to temperature differences is avoided, ensuring the quality of the fruits and vegetables.

[0079] The top gas channel 172 is located above the storage device 130 along the height direction of the refrigerated container 100, and the top gas channel 172 is in close contact with the storage device 130, enabling the gas in the top gas channel 172 to exchange heat with the gas at the top in the storage device 130, and enabling water droplets to condense in the top sandwich layer of the storage device 130. In particular, enabling water droplets to condense on the inner surface of the outer top plate 152 in the top sandwich layer.

[0080] Combined Figure 4 As shown, the gas channel 171 may include two side gas channels 173, and the two side gas channels 173 are arranged opposite to each other along the width direction of the heat-insulating container bag. The storage device 130 is located between the two side gas channels 173. Both of the two side gas channels 173 communicate with the top gas channel 172, and the gas in the top gas channel 172 can enter the two side gas channels 173 respectively. The side gas channel 173 is located on the side of the storage device 130 along the width direction of the refrigerated container 100, and the side gas channel 173 is in close contact with the storage device 130, enabling the gas in the side gas channel 173 to exchange heat with the gas at the side in the storage device 130, and enabling water droplets to condense in the side sandwich layer of the storage device 130. In particular, enabling water droplets to condense on the inner surface of the outer side plate 153 in the side sandwich layer.

[0081] The gas passage 171 further includes a bottom gas passage 175 which is in communication with both the side gas passage 173 and the end gas passage 174. The bottom gas passage 175 is in communication with the top gas passage 172 through the side gas passage 173. The gas in the side gas passage 173 can enter the end gas passage 174 through the bottom gas passage 175. The bottom gas passage 175 is in communication with both of the two side gas passages 173, and the gas in the two side gas passages 173 can enter the bottom gas passage 175. The bottom gas passage 175 is located below the storage device 130 along the height direction of the refrigerated container 100 and is in close contact with the storage device 130, so that the gas in the bottom gas passage 175 can exchange heat with the gas at the bottom in the storage device 130, enabling water droplets to condense in the bottom interlayer of the storage device 130. In particular, water droplets can condense on the inner surface of the outer bottom plate in the bottom interlayer.

[0082] The end gas passage 174 is located beside the storage device 130 along the height direction of the refrigerated container 100. The end gas passage 174 and the opening 133 of the storage device 130 are respectively located at both ends of the box body 110 along the length direction of the refrigerated container 100. Of course, the end gas passage 174 and the sealing plate can be respectively located at both ends of the box body 110 along the length direction of the refrigerated container 100. The end gas passage 174 is in close contact with the storage device 130, so that the gas in the end gas passage 174 can exchange heat with the gas at the end in the storage device 130, enabling water droplets to condense in the end interlayer of the storage device 130. In particular, water droplets can condense on the inner surface of the outer end plate in the end interlayer.

[0083] The end gas passage 174 is in communication with the bottom gas passage 175, and the gas in the bottom gas passage 175 can enter the end gas passage 174. The end gas passage 174 can also be in communication with the two side gas passages 173, and the gas in the two side gas passages 173 can enter the end gas passage 174. The end gas passage 174 is also in communication with the refrigeration device 103, and the gas in the end gas passage 174 can flow back to the refrigeration device 103. Of course, for the convenience of processing and assembly, the end gas passage 174 can also be in communication with the top gas passage 172.

[0084] To improve the sealing performance of the storage device 130, such as Figure 2 and Figure 3As shown, the refrigerated container 100 further includes a sealing device 180, which is located on the side of the storage device 130. The sealing device 180 is connected to the inner wall panel 111. Optionally, the sealing device 180 can be configured as a sealing door, and the sealing device 180 can be connected to the inner side wall 114 through a connecting member 181. The sealing device 180 is also spaced apart from the storage device 130 to form a spaced space 134, and the spaced space 134 communicates with the opening 133 to communicate with the storage space. Thus, the storage capacity can be expanded. To further increase the storage capacity, the sealing device 180 can also be integrally formed with the door 105. Of course, the sealing device 180 can be configured as a sealing curtain, and the sealing curtain can be connected to the inner top wall 113 through a connecting member 181 for easy opening and closing. Preferably, a plurality of support rods (not shown) can also be provided in the spaced space 134, and the plurality of support rods can be used to abut against the goods to prevent the goods from tipping over.

[0085] The spaced space 134 is separated from the gas channel 171 by a sealing plate to prevent the gas in the gas channel 171 from entering the interior of the storage device 130 through the spaced space 134, thereby affecting the sealing performance of the storage device 130. Specifically, the spaced space 134 is separated from the top gas channel 172 by a top sealing plate 162, and the spaced space 134 is separated from the side gas channel 173 by a side sealing plate 163.

[0086] Optionally, to ensure the air pressure balance in the storage device 130, as Figure 6 shown, the refrigerated container 100 further includes a balance air bag 139, and the balance air bag 139 communicates with the storage device 130 to solve the problem of negative pressure during the controlled atmosphere preservation process and avoid damage to the storage device 130 and ineffective opening of the door 105 and the sealing device 180 due to air pressure imbalance.

[0087] As Figure 5 shown, the refrigerated container 100 further includes a floor 106, and the gas channel 171 further includes a bottom gas channel 175 that communicates with the side gas channel 173.

[0088] The refrigerated container 100 further includes a plurality of floors 106, and the plurality of floors 106 can be spaced apart to form the bottom gas channel 175. The plurality of floors 106 can be spaced apart along the width direction of the refrigerated container 100. The floor 106 can be a T-shaped floor. One end of the bottom gas channel 175 in the length direction of the refrigerated container 100 is open, and the other end is closed. In this way, the gas in the bottom channel is prevented from entering the spaced space 134. Of course, the floor can also be other forms of floor structures, and this embodiment does not intend to limit this.

[0089] Specifically, one end of the multiple floors 106 close to the refrigeration device 103 along the length direction of the refrigerated container 100 is open, and one end of the multiple floors 106 close to the door 105 along the length direction of the refrigerated container 100 is closed. Thereby, the gas between the two floors 106 is prevented from entering the spacer 134 and then entering the storage device 130 through the opening 133.

[0090] Furthermore, as Figure 6 shown, in order to ensure that gas can enter between the multiple floors 106, one end of the floor 106 close to the door 105 has a plurality of second through holes 135. The gas can enter between the adjacent floors 106 through the plurality of second through holes 135. One end of the floor 106 close to the refrigeration device 103 may not be provided with through holes, so as to ensure that the gas flows from the direction of the door 105 towards the direction of the refrigeration device 103, ensuring the refrigeration effect, enabling the gas in the bottom gas passage 175 to flow stably, and avoiding uneven temperature in the storage device 130.

[0091] The storage device 130 further includes a storage floor 136, and the storage floor 136 is located above the floor 106 along the height direction of the refrigerated container 100. The multiple floors 106 support the storage floor 136. The storage floor 136 is a single-layer board structure. The storage floor 136, the inner side plate 143, and the inner top plate 142 can jointly enclose the opening 133, and the sealing plate can be arranged around the opening 133. The storage floor 136 is connected to the outer plate. Two sides of the storage floor 136 along the width direction of the refrigerated container 100 can be respectively connected to the two outer side plates 153. One end of the storage floor 136 along the length direction of the refrigerated container 100 can be connected to the outer end plate, and the other end of the storage floor 136 along the length direction of the refrigerated container 100 can form a part of the opening 133.

[0092] As Figure 5 shown, the storage floor 136 is spaced apart from the bottom end of the inner plate along the height direction of the refrigerated container 100, thereby facilitating the cleaning of the water droplets in the interlayer 131. The storage floor 136 is spaced apart from the bottom end of the inner side plate 143, and the storage floor 136 is spaced apart from the bottom end of the inner end plate. The water droplets in the interlayer 131 fall due to the action of gravity and land on the storage floor 136, facilitating cleaning. Further, the storage device 130 further includes a water storage tank 137, and the water storage tank 137 is connected to the storage floor 136 and the outer plate (outer side plate 153). The water storage tank 137 is recessed downward along the height direction of the refrigerated container 100. Thus, the water droplets can fall into the water storage tank 137, facilitating drainage.

[0093] As Figure 4As shown, preferably, in order to facilitate the discharge of water droplets in the top interlayer, the middle part of the inner top plate 142 bulges upward. Preferably, in a plane parallel to the width direction of the refrigerated container 100, the cross-sectional shape of the inner top plate 142 is configured as a substantially arc shape. The middle part of the inner top plate 142 is higher than both sides of the inner top plate 142 along the width direction of the refrigerated container 100. The air in the top interlayer can condense into water droplets on the inner surface of the outer top plate 152 when cooled. The water droplets drip onto the inner top plate 142 and flow to both sides under the action of gravity and finally fall into the water storage tank 137.

[0094] Furthermore, the storage device 130 also has an openable door for communicating the inside of the storage device 130 and the gas passage 171. In this way, the gas in the gas passage 171 can first enter the inside of the storage device 130 through the door to pre-cool the inside of the storage device 130, and the pre-cooled storage device 130 is used for transporting fruits and vegetables. When the door is opened, the refrigerated container 100 does not transport goods. Specifically, as Figure 4 shown, a return air door 186 can be provided at the end of the storage device 130, and the return air door 186 can communicate with the end gas passage 174. As Figure 6 shown, an air outlet door 187 can also be provided on the side of the storage device 130, and the air outlet door 187 can communicate with the side gas passage 173. Both the return air door 186 and the air outlet door 187 can be opened by electric, pneumatic or mechanical means. Of course, according to the actual situation, both the return air door 186 and the air outlet door 187 can also be remotely opened.

[0095] A lighting device 138 is also provided in the storage device 130 to illuminate the storage space. Preferably, a camera, a temperature sensor, a humidity sensor, a wireless transmission module, etc. are also provided in the storage device 130 for real-time remote monitoring to accurately grasp the situation of the goods in the box and effectively avoid losses caused by the deterioration of the goods during transportation.

[0096] During actual operation, the refrigeration device 103 can pre-cool the inside of the box body 110 in advance. Open the refrigeration device 103, the return air door 186 and the air outlet door 187. The cold air from the air outlet of the refrigeration device 103 flows through the top gas passage 172, the side gas passage 173, the bottom gas passage 175 and the end gas passage 174. The cold air in the end gas passage 174 enters the storage device 130 through the return air door 186 to reduce the temperature of the internal storage space of the storage device 130. The cold air in the storage device 130 can enter the side gas passage 173 through the air outlet door 187 and then circulate back to the refrigeration device 103. In this way, the goods can be pre-cooled in advance, saving energy and reducing transportation costs.

[0097] When the temperature in the storage device 130 drops to a certain temperature, the box door 105 and the sealing device 180 are opened, the return air door 186 and the air outlet door 187 are closed, and goods can enter the storage space of the storage device 130 through the box door 105 and the sealing device 180. The cold air in the gas passage 171 no longer enters the storage device 130 through the return air door 186 and the air outlet door 187, and the cold air in the gas passage 171 is separated from the interior of the storage device 130 by a sealing plate. The cold air in the gas passage 171 circulates around the storage device 130 outside the storage device 130 to maintain the low temperature inside the storage device 130 and prevent the temperature inside the storage device 130 from rising to ripen fruits and vegetables. The controlled atmosphere device 102 is turned on, and using the working principle of controlled atmosphere preservation, the composition of the gas inside the storage device 130 is adjusted to inhibit the respiration of fruits and vegetables and keep them in a dormant state, so as to achieve the effect of ultra-long preservation of fruits and vegetables without deterioration of quality.

[0098] The storage device 130 of the refrigerated container 100 provided by the present invention has good sealing performance, can realize multimodal transport of highway, railway and sea, is not restricted by the transport form, and realizes direct transport from the place of origin to the table. When transporting fruits and vegetables, the cold air circulation of the refrigeration device 103 is isolated outside the storage device 130, and the gas outside the storage device 130 does not enter the interior of the storage device 130, avoiding changes in the composition and content of the gas inside the storage device 130, inhibiting the respiration of fruits and vegetables, and ensuring the preservation effect and the quality of fruits and vegetables.
